Examining Attentional Biases Elicited by Sexual Stimuli Using MouseView.js: An Online Paradigm to Mimic Eye Movements

Attention is a key mechanism underlying many aspects of sexuality, with eye-tracking studies revealing that attention is both sustained by sexual stimuli and corresponds with sexual interest. Despite its utility, eye-tracking experiments typically require specialized equipment and are conducted in a laboratory setting. The overarching objective of this research was to assess the utility of a novel online method, MouseView.js, for assessing attentional processing of sexual stimuli outside of a laboratory context. MouseView.js is an open-source, web-based application where the display is blurred to mimic peripheral vision and an aperture is directed using a mouse cursor to fixate on regions of interest within the display. Using a discovery (Study 1, n = 239) and replication (Study 2, n = 483) design, we examined attentional biases to sexual stimuli among two diverse samples with respect to gender/sex and sexual orientation. Results revealed strong attentional biases toward processing sexual stimuli relative to nonsexual stimuli, as well as dwell times that correlated with self-report sexuality measures. Results mirror those observed for laboratory-based eye-tracking research, but using a freely available instrument that mirrors gaze tracking. MouseView.js offers important advantages to traditional eye-tracking methods, including the ability to recruit larger and more diverse samples, and minimizes volunteer biases.

Examining Visual Attention Patterns among Asexual and Heterosexual Individuals

Asexuality has garnered much attention, and empirical data support its classification as a sexual orientation. Asexuality is defined as a lack of sexual attraction to others, with approximately 1% of the population falling in this category. As theoretical models situate attention as a central component of sexual response, the current study examined attentional processing of erotic stimuli in asexuals and heterosexuals. We hypothesized that heterosexual participants would have initial and controlled visual attention patterns favoring erotic images over non-erotic images. We predicted that asexual participants would have significantly smaller or non-existent differences in attention to erotic versus non-erotic images. Ninety-five adults completed an eye-tracking task viewing erotic and non-erotic images. Eye-tracking data showed no group differences in initial attention to erotic images. For controlled attention, there was a large effect size in the hypothesized direction. Heterosexual participants exhibited more and longer fixations on erotic images, whereas asexuals exhibited a more even distribution of attention across image types. Exploratory analysis of group differences in the association between visual attention and ratings of sexual attractiveness revealed a complex pattern of differences, with some indication of a stronger association between total fixation and sexual attraction for heterosexual participants. These findings suggest that differences in attention to sexual stimuli may represent key underlying differences between asexual and allosexual orientation. Findings also contribute to the larger literature on visual attention and attraction.

Gynephilic Men's and Androphilic Women's Visual Attention Patterns: The Effects of Gender and Sexual Activity Cues

Men and women differ in the degree of specificity of sexual response and differences in attention to sexual cues may be a mechanism underlying these gendered patterns. The majority of previous research has examined attention using static images, which differ considerably from the dynamic videos used in studies of sexual response. To test attention as a potential mechanism involved in gendered sexual response, we used eye-tracking to examine visual attention patterns of 33 gynephilic men and 36 androphilic women to videos depicting preferred and nonpreferred gender targets engaging in varying sexual activities. Specificity of controlled attention was gendered, and this effect differed depending on the intensity of sexual activity cues depicted. Regardless of sexual activity cues, men's controlled attention was gender-specific toward preferred targets. Sexual activity cues did, however, impact the degree to which women's controlled attention was gender-specific. Specifically, women's attention was gender-specific to low-intensity stimuli but nonspecific for masturbation and same-sex dyadic stimuli. Women's attention was gender-specific for mixed-sex dyadic stimuli, but with greater attention directed toward nonpreferred gender targets. Overall, contextual cues impact women's attention to a greater degree than men's. Potential explanations for these findings and implications of stimulus selection for sexuality research are discussed.

Attention Bias and Recognition of Sexual Images in Depression

Depression greatly affects sexuality. Theoretical and empirical evidence account for the existence of attention bias to sex-related stimuli. This attention bias might be impaired in depression, resulting in sexual problems. A sample of 13 patients with depression and 13 matched healthy controls were tested using the dot-probe and picture recognition task to measure attention to erotic images. No difference in attention to sex-related stimuli (ω² = 0, p = 0.22) and in memory bias (ω² = 0, p = 0.72) was found between the two groups. Explorative analyses were conducted to identify the sexual content-induced delay effect in the data, assess variability differences, and compare trial-level bias score-based indexes between groups. Across all analyses, there was little evidence for depression affecting sexual-related cognitive processing, and even this might be explained by other means. Our results suggest that restrained attention is probably not the main factor behind sexual problems in depression.

Canadian undergraduate men's visual attention to cisgender women, cisgender men, and feminine trans individuals

Some heterosexual men express sexual interest in feminine trans individuals with penises. It is possible that this interest arises from a tendency for heterosexual men to be sexually responsive to gender in addition to sex. We compared the self-reported sexual attraction and visual attention patterns of Canadian undergraduate heterosexual men (N = 51) and gay men (N = 20) to nude images of feminine trans individuals with penises, cisgender men, and cisgender women. Heterosexual men were most attracted to cisgender women and fixated on them the longest. However, they were more attracted to feminine trans individuals with penises than to cisgender men. They also biased their attention to feminine trans individuals with penises over cisgender men. This pattern was unique to heterosexual men. Gay men were most attracted to cisgender men and allocated the most visual attention to them. They responded to feminine trans individuals and cisgender women in a relatively similar manner. As such, heterosexual men appear to be responsive to sex and gender, which may account for sexual interest in feminine trans individuals among some heterosexual men.

Attention Bias and Recognition of Sexual Images

Attention to sexual stimuli is necessary for the development of sexual response, yet while there is some evidence of attention bias in favor of sexual stimuli, the direction and magnitude of the effect remain unknown. A high-powered sample of 113 participants was tested using the dot-probe task (DPT) and picture recognition task (PRT) to measure visuospatial attention to erotic images. Participants showed no attention bias in the DPT (r_B = 0.201, p = 0.064) but were significantly better at recognizing erotic rather than neutral or training pictures (d = 1.445 and 1.461, respectively, both p < 0.001). This indicates that spatial attention bias to sexual pictures is small, negligible, possibly even non-existent, or else the DPT is not a reliable tool to assess it. Results of the PRT, on the other hand, show that sexual stimuli are prioritized in memory and this should be explored in future research.
